The electronic properties of single-walled metallic carbon nanotubes can be effectively captured by a system of interacting electrons in one dimension. As shown by both theory and experiment, and as discussed here, the nanotube thus exhibits signatures of Luttinger liquid behaviour. Furthermore, as a consequence of Luttinger liquid physics, we find that nanotubes are expected to display bizarre phenomena such as charge fractionalization; anamolous suppression of Andreev current when contacted to superconductors; hosting of entangled quantum states from a superconducting source.
